Title: Near infrared diagnostic method and instrument
Inventor: HELFER JEFFREY L
IPC: A61N5/06
Filed: 1991-02-08
Abstract: NEAR INFRARED DIAGNOSTIC METHOD AND INSTRUMENT  ABSTRACT        There are disclosed an instrument and method for using near IR to discriminate between healthy and diseased tissue, using, e.g., a catheter and a spectrophotometer.  Near IR is passed at certain wavelengths to suspected tissue, and reflected light is analyzed to determine the absorbance, and preferably the second derivative thereof.  From identification of the absorption spectra of known diseased and known healthy tissue, a relation has been established to determine the following correlation equation for determining the predictive value of y: y = Co + C1A(.lambda.1) + C2A(.lambda.2) wherein A(.lambda.1) + A(.lambda.2) are the second derivatives for the absorbance at the two selected wavelengths.  For blood cholesterol esters and plaque, .lambda.1 is preferably 1714.5 ant .lambda.2 is preferably 1678.5 nm.  Solving for the coefficients Co, C1 and C2, it has been shown that values of y less than -8.0 represent diseased tissue, which should be treated.  Ablation laser treatment is described as one mode of treatment.

Abstract: In general, existing pet doors are unnecessarily complicated and consequently expensive to produce and/or install.  The pet door of the present invention overcomes these problems and provides a readily visible indication of whether a pet is inside or outside a house.  The pet door disclosed herein includes a pair of simple rectangular frames carrying a flexible flap with a weighted bottom end for overhanging inner and outer ledges on the bottom ends of the frames, inside or outside of the frames depending upon the location of the pet, i.e. a pet moving through the door will push the flap through the frames, the weight returning the flap to a closed position in the frames with the weight against one bottom ledge.

Abstract: ABSTRACT OF THE DISCLOSURE       Apparatus for converting an input note signal of the type having a rapid rise and a slow exponential decay into an output note signal which, from the shape of its envelope, appears to be a time reversed version of the input note signal includes means for forming a normalized envelope signal, En, and means for modifying the instantaneous gain applied to the note signal as a function of the instantaneous amplitude of En.  Ideally, the function is proportional to the inverse of the square of the instantaneous amplitude of the normalized envelope signal, En.          The note signal gain modification means in accordance with a first embodiment includes an analog-to-digital converter fed by En which addresses a ROM lookup table containing data words corresponding to gain amplitudes.  In a second embodiment of the note signal gain modification means, the dynamic range of En is divided into regions and current sources are selected for charging a capacitor depending on in which region the instantaneous amplitude of En lies, to select in each region a slope versus time of the gain amplitude.

Abstract: ABSTRACT                     SYSTEM AND METHOD FOR DYNAMIC CONTROL OF HORIZONTAL SCROLLING     A method and system for dynamically controlling the horizontal scrolling of data contained in a stored table of arbitrary size in a windowing environment.  The list of data to be scrolled through is stored in memory with certain columns designated as sticky.  Responsive to input from the user, a process is invoked to either scroll left or right through data contained in the stored list.  A "must display" column is determined based on the current display in the window and the direction of scrolling.  The sticky columns that can fit with the "must display" column are determined and placed on the display.   Sticky columns that cannot be placed on the display with the "must display" column due to window   size   limitations   are   temporarily   suppressed. Additional non-sticky columns are placed on the display on a space-available basis including the placement of a partial column that fills the display.
